DETAILED DESCRIPTION

In the following description, specific details are given to provide athorough understanding of the embodiments. However, it will beunderstood by one of ordinary skill in the art that the embodiments maybe practiced without these specific details.

Overview

The present application is directed to motor driven vehicles. In oneembodiment the motor driven vehicle is a trike that utilizes acustomized three wheel rear truck assembly to create a completely novelriding experience. The rear truck assembly of the motor driven vehiclemay be comprised of a skateboard truck and wheels along with a thirdcenter caster wheel on a custom caster assembly that allows the centercaster wheel to rotate 360° independently from the outer skateboardwheels. The size of the skateboard truck may vary in size according tothe needs of a user, however the drawings are shown with very wideskateboard truck as an example. The center caster wheel may comprise abracket assembly that holds the wheel at a fixed distance that is lowerthan the outer wheels. By having the center wheel lower than the outerwheels it creates a riding experience similar to wake boarding, surfingand snowboarding combined.

When a rider has the board balanced on the center caster wheel the outerwheels are not touching the ground which creates a lateral rocker effectvery much like a snowboard. The rider is able to tilt the boardlaterally in both directions and use the outer skateboard wheel on thatside as a friction point against the ground. Due to the center casterwheels ability to rotate 360° when friction is applied to the outerwheel, the board initiates a carving maneuver that is very similar tothe carving maneuver of a snowboard or surfboard. With the correctapplication of balance and pressure, a skilled rider can perform S-turnsand power slide sideways while remaining on the board traveling straightahead.

An additional novel feature of this device is the motorized front wheeland electric battery. Optionally, the battery may be removable. Thefront wheel has an electric motor controlled by a throttle mounted tothe handlebars. A battery pack is mounted to the center shaft just abovethe fork of the front wheel. Alternatively, a rechargeable battery maybe located in a housing mounted on the top front end of the board. Bycombining a front wheel drive single bicycle wheel and handlebars to thethree wheeled skateboard truck and caster assembly on the back of theboard, the rider is given the ability to use variable acceleration tomimic the ride experience of a wakeboard being pulled by a motor boat.The front wheel essentially acts like the motorboat which can turn andprovide acceleration in any direction. The skateboard connecting thefront wheel to the rear wheels acts like the tow rope between boat andwakeboard transferring the acceleration and change of direction to therear wheels with a predictable and constant delay of the transfer offorce.

Furthermore, the rider standing on top of the board holding onto thehandlebars acts as both the driver of the motor boat and the rider ofthe wakeboard using a combination of throttle, front wheel friction,rear wheel friction, and balance to carve the board and performsurfing/snowboarding/wakeboarding maneuvers. In addition to thethrottle, there is a front wheel brake assembly that add yet anotherpoint of control making the ride experience that much more novel. Thereis no other board-sport device on the market that functions the way thatthis motor driven vehicle does.

As shown, the motor driven vehicle 100 may include a board (or deck) 102having an upper (top) surface and an opposing lower (bottom) surface, acaster assembly 109 and a rear truck assembly 104 secured to the lowersurface of the board 102. Additionally, the motor driven vehicle 100 mayinclude a motor control system 106 secured to an upper surface of theboard 102.

The rear truck assembly 104 may include a skateboard truck 108 securedto the bottom of the board 102. The skateboard truck 108 may include anaxle 111 having outer rear wheels 110 attached at each end of the axle111. The rear truck assembly 104 may further include a rubber bushing115 mounted to a rear truck plate 125, mounted to the bottom of theboard 102 on a first end, and a housing 117 secured to the axle 111 ofthe skateboard truck 108 on a second end. The rear truck plate 125 maybe detachable fastened to the bottom of the board 102 by bolts or anyother known fastener in the art.

According to one aspect, a rider may remove a portion of the axle thatconnects to an outer rear wheel 110 and replace it with differentlengths extender axles to customize the ride experience. The rear truckassembly 104 can be one solid piece without the ability to remove and/orextend the axle, however this feature provides for greater variabilityof the motor driven vehicle.

The caster assembly 109 may comprise a wheel mount assembly 112 fordetachably mounting a center caster wheel 114 onto the bottom surface ofthe board 102. The wheel mount assembly 112 allows the center casterwheel 114 to rotate 360° about its center axis 115. (See FIG. 4)According to one aspect, the wheel mount assembly 112 may be comprisedof a U-shaped bracket 116, a swivel plate 118, a base 119 and adetachable caster mounting plate 120. The U-shaped bracket receives thecaster wheel 114 which is bolted or secured, by any fastening meansknown in the art, onto the sides of the U-shaped bracket 116. A topsurface, integrally connected to the sides, of the U-shaped bracket 116may be rotatably mounted to the swivel plate 118 by the base 119, wherethe swivel plate 118 allows the caster wheel 114 to rotate 360° aboutits center axis 115 as mentioned above. The swivel plate 118 may bemounted to the caster mounting plate 120 using any fastener or meansknown in the art and the wheel mount assembly 112 may be detachablymounted to the board 102 by bolting the caster mounting plate 120 to thebottom surface of the board 102 or using any other known method in theart. The caster mounting plate 120 is detachable from the base 119.

Turning to FIG. 3, the motor control system 106 according aspects of thedisclosure described herein is shown. The motor control system 106, maycomprise a controller 122 in electrical communication with arechargeable battery 124 located in a housing 123, as well as a motor126, a throttle 128 and a brake lever 130. The rechargeable battery 124may be recharged using a removable cable 132 plugged into a standardelectrical outlet 134.

The controller 122 may be customized by the rider. Controllers thatallow the rider to connect batteries of higher voltage can be utilized,as well as software designed for a specific controller that allows therider to adjust all aspects of the motor's function. This includes butis not limited to the maximum current allowed through the motor 126, theacceleration ramp up and ramp down times, and any form of regenerativebraking or activity of the motor. The controller can be used to limittop speed and acceleration to create a safer riding experience for therider.

According to one aspect the housing 123 may be mounted onto the topfront end of the board 123 and extend upwardly to a hollow elongatedtubular member 142. A steering post 144 may be mounted to or within afirst end 142 a of the hollow elongated tubular member 142 and extendupwardly to a handlebar mounting member 146 for mounting handlebars 148to the steering post 144. Located on the handlebars 148 are the throttle128 mounted on a first handle portion and the brake lever 130 mounted toa second handle portion. A second opposing end of the hollow elongatedtubular member 142 includes a fork 142 b mounted to a hub assembly 136of a front wheel 138, described below.

According to one aspect, the motor driven vehicle 100 may include forksuspension 133 as shown in FIG. 1. This feature of the vehicle 100allows for the use of a fork 142 b with hydraulic suspension that isdesigned for a first sized wheel on a second sized wheel, where thefirst and second sized wheel are different. For example, the first sizedwheel may be a 20 inch wheel and the second wheel may be a 16 inch hubmotor. By modifying the studs on the front of the fork 142 b andattaching a customized break mounting system, mechanical caliper orclamp brakes can be used with a second sized wheel. The suspension iscritical when turning or drifting the vehicle 100 at high velocitiesbecause it keeps the front wheel from chattering or bouncinguncontrollably during the turn. Due to the weight of the front wheelmotor, the suspension is necessary for the user experience to be bothsafe and enjoyable. Other variations of this feature may includedifferent types of suspension other than hydraulics and may also includedisc braking systems or various other types of manual clamping breaks.

According to one aspect, the motor driven vehicle 100 may include lightemitting diodes 150 allowing the vehicle 100 to be easily seen at night.Although the light emitting diodes 150 are shown on the fork 142 b, thisis by way of example on. The light emitting diodes may be locatedanywhere on the motor driven vehicle 100 and the number of lightemitting diodes 150 may vary. The battery 124 and controller 122 in themotor control system 106 may be utilized to control power to the lightemitting diodes 150 to turn them On and Off.

As is known in the art, a rider utilizes the throttle 128 and brakelever 130 to control the movement of the motor driven vehicle 100. Thethrottle 128 sends signals to the controller 122 which in turn sends asignal to the motor to power the motor 126, via the battery 124, toallow the rider to propel the motor driven vehicle 100 in a forwarddirection. The rider can increase or decrease the power to the motor126, which in turn controls the speed of the motor driven vehicle 100,using the throttle 128. That is, the throttle 128 is used to regulatethe speed of the motor driven vehicle 100. The motor 126 may be locatedin a hub assembly 136 of a front wheel 138 of the motor driven vehicle100. The brake lever 130 is utilized by a rider to slow the motor drivenvehicle 130. When the rider presses on the brake lever 130 a signal issent to the controller 122 to decrease power supplied to the motor 126and cause a force to be applied to a pair of friction pads 140 to therim of the front wheel 138 for slowing or stopping the motor drivenvehicle 100. Any other braking system known in the art may be utilized.

The hollow elongated tubular member 142 may house the wiring and cablingfor electrically connecting the motor 126, battery 124 and lightemitting didoes 150 (optional) to the controller 122.

The motor driven vehicle 100 may further comprise a stiffener 152mounted to the bottom of the board 102 for providing variable boardflexibility. As shown in FIG. 8, the stiffener 152 may be formed from aflat elongated member made from metal or any other material known in theart. The stiffener 152 may extend along a horizontal axis from a firstend of the board 102 to the caster assembly 109. The stiffener 152 ismounted to the bottom of the board 102 by bolts 154 or any other type offastener known in the art. The bolts 154 may be removable by the riderallowing the rider to change the stiffness of the board 102. Forexample, FIG. 3 shows that four bolts are used to secure the stiffener152 to the bottom of the board 102. If the middle bolts 154 a, 154 b areremoved, the distance between the first bolt 154 c and the fourth bolt154 d is increased which allows a greater area of the board 102 to flex.The stiffener 152 is utilized to stiffen the board 102 and the morebolts that are used to secure the stiffener 152 results in a board thatis stiffer than a board 102 with fewer bolts.

In other words, the stiffener allows the rider to control how much theboard 102 flexes when weight is applied given different placements ofthe feet of the rider on the board 102. According to one example, thestiffener 152 may be an elongated aluminum plate that extends a portionof the way back from the front of the board 102. The further thisaluminum plate extends the more stiff the board will be. According toanother aspect, the stiffener 152 may be a rod system located along thebottom (or within the board 102) that would allow the rider to slide arigid rod further back and lock it in place giving the rider the abilityto change the flexibility of the board 102 immediately and customize theride experience at any time. Other variations may include, but are notlimited, to using tension lines and/or electronic board firmingmechanisms that could be adjusted manually or remotely. Variability ofthe board's flexibility is essential for providing the correct rideexperience and allowing the rear wheels 110 to contact the ground in theappropriate fashion.

As shown in FIG. 4 the caster wheel 114 may be located at a pre-setdistance “X” from the bottom of the board to the ground. When in aninitial configuration or standing position, the rear wheels 100 may belocated at a pre-set distance “Y” from the bottom of the board 102. Thepre-set distances of “X” and “Y” may be adjusted by the thickness of thedetachable caster mounting plate 120 and/or the size of the caster wheel114. The thicker the caster mounting plate 120 the smaller “X” becomeswhile the thinner the caster mounting plate 120 is the larger “X”becomes. Similarly, the larger the caster wheel 114 the smaller “X”becomes while the smaller the caster whe is the larger “X” becomes.

FIG. 5 is a back elevation view of the rear truck assembly 104. Asshown, when in the initial configuration, the rear wheels 110 do nottouch the ground by a distance “Z”. When in the initial position, theangle between the housing 123 on the board 102 and the ground is 90degrees. In other words, the board 102 is balanced on the center casterwheel. To reduce the distance “Z” for one of the rear wheels 110 totouch or make contact with the ground, the angle must be reduced. Therider can reduce the distance “Z” by tilting the board towards theground. As can be seen in FIGS. 6 and 7, which the rider can selectwhich of the rear wheels 110 will touch the ground based on whether theboard 102 is tilted to the left or the right.

A pair of springs 156 may be mounted between the back end of the board102 and the axle 111 of the rear truck assembly 104 on opposing sides ofthe board 102. The pair of springs 156 provide the rider more control ofthe motor driven vehicle 100. For example, a slight unintended move willnot cause the board 102 to tilt to one side or the other, the rider willhave control over the tilt of the board 102 based on the force that isput into the titling of the board 102. As shown in FIG. 6, when theboard 102 is tilted the left, the left spring compresses while the rightspring expands. Conversely, as shown in FIG. 7, when the board 102 istitled to the right, the right spring compresses while the left springexpands. The pair of springs 156 may be mounted to the board 102 bywrapping around lower posts 158 located on the axle 111 and upper posts160 located on the bottom of the board 102.

FIG. 9 is a diagram representative of a kit 162 configured customizingthe motor driven vehicle 100 based on the needs and desires of therider. The kit 162 may include a plurality rear wheels in differentsizes, a plurality of casters in different sizes, a plurality of castermounting plates 120 in different thicknesses and a plurality of reartruck plates 125 in different thicknesses. FIG. 10 is a perspective viewrepresentative of the parts contained with the kit for the motor drivenvehicle. As explained previously, the thicknesses of the plates 120, 125and the sizes of the caster wheel and rear wheels can be selected by therider to assemble the motor driven vehicle to the needs of the rider.

FIG. 11 is a back elevation view of the rear truck assembly of the motordriven vehicle showing a different size caster and different sizedmounting plates changing the distances from these components from X toX′; from Y to Y′ and Z to Z′.
